The Kansas City Chiefs tight end Travis Kelce shocked his fans when he took the stage to perform with his girlfriend Taylor Swift on her Eras Tour for the first time over the weekend. It has since been revealed that afterwards, Kelce and Swift partied together in London until 4am!

Kelce And Swift Party All Night

During Swift’s third show at Wembley Stadium in London on Sunday night, Kelce took the stage with Swift for her “I Can Do It With a Broken Heart” outfit change. Afterwards, the couple headed to the celebrity hotspot Chiltern Firehouse, where the 34 year-old lovebirds proceeded to party all night.

For this night of partying, Swift wore a colorful crochet mini dress that featured long, slightly flared sleeves. She completed her look with a pair of open-toe chunky heeled sandals and a brown bag that she wore over her shoulder.

As for Kelce, he went for a more casual look. He was seen wearing a loose white shirt with matching pants and a blue bucket hat. Check out their looks in the photo below.

Kelce Performs With Swift – Meets Royals

This was far more low-key than the look that Kelce was wearing onstage earlier in the night, however. For his Eras Tour debut, Kelce wore a tuxedo and top hat. He picked up Swift and carried her before putting her down gently on a red couch in the center of the stage.

Check out his Eras Tour debut in the video below.

This came two days after Kelce and Swift met Prince William and his two oldest children Prince George and Princess Charlotte. The royals had attended Swift’s first London show on Friday night, which was William’s 42nd birthday.

“Happy Bday M8! London shows are off to a splendid start,” Swift wrote alongside a photo of herself and Kelce with the royals.

Kelce And Swift’s History

Kelce and Swift went public with their relationship in September of last year. After that, Swift became a fixture at Kansas City Chiefs games, cheering Kelce’s team on all the way to their Super Bowl win in February.

During the NFL offseason, Kelce has traveled the world with Swift on her Eras Tour. He’s attended her concerts at various spots in Australia, Asia, South America, and Europe.

Kelce and Swift are arguably the most popular couple in the world right now. Back in January, Page Six alleged that Travis and Taylor were planning to get engaged this summer.

“Taylor and Travis discussed it and there is a plan,” an insider claimed at the time. “They will get engaged on their one-year anniversary in July.”

However, another source quickly fired back by saying that “there are still no plans for an engagement. It’s still new, and they’re happy and still getting to know each other,” according to Elle Magazine.

Whether Kelce and Swift end up getting engaged or not, it’s nice to see that they appear to be having a blast with one another. Good for them for blowing off some steam in London together after her concert!
